make compatible with ILI lib, plus minor fixeups.

- fix library.properties
- minor cleanup on scrollTo (ported back from ILI lib)
- ported drawBitmap back from ILI lib.
- Added ILI defines in .h so that WROVER can be dropped in place
  for code that used to use the ILI library.
- Added min/max to override the bad versions that come from arduino libs
  (even the examples/graphicstest will not compile without those).
